Ligand Determination of a Copper Complex by Cu 2p X-Ray Photoelectron Spectroscopy

Abstract

The copper 2p X-ray photoelectron spectra (XPS) of cupric complexes, the structures of which have been well characterized, were measured. The intensity of the so-called "shake-up" satellite relative to the main line was also measured. It was found that the satellite intensity decreased as the cupric complex became covalent. It was also found using this satellite intensity that a cupric complex of (S)-3-aminohexahydroazepine (abbreviated as S-ahaz), [Cu(S-ahaz)2](BF4)2, is directly coordinated by an F atom. © 1994, The Japan Society for Analytical Chemistry.
